I cheat and lie of resumes and academic referrences as well as affiliations while having a few published article in mathematics and other successful professional experiences at work.
I will break the rules and harm people and literally no one will stop me just as before.

Claim: [math] 0.999_{\dots} \neq 1[/math]

Proof: We use induction. The base case is trivial: [math] 0.9 \neq 1[/math]. Next we introduce the notation that [math]0.9_n = \underbrace{0.9999999}_{n-\text{many nines}}[/math] is the decimal with n-many 9s.

Now the inductive step: we assume [math]0.9_n \neq 1[/math]. Then trivially [math]0.9_{n+1} \neq 1 [/math]. It might help to notice that [math] 1 - 0.9_{n+1} \neq 0[/math].

This implies that [math]0.9_n \neq 1 \qquad \forall n\in \mathbb{N}[/math]

Finally, we define [math] 0.999_{\dots} := \lim_{n\to\infty} 0.9_n[/math].

[math]\therefore 0.999_{\dots} \neq 1 \qquad \square [/math]

lmao, ok retard.

OP’s induction does not actually ever reach the case where 0.999… has an infinite number of 9s. Infinity is not in the naturals, and the induction only ever iterates over the naturals.

The limit written after not being equal to 1 is a non sequitur and incorrect.

Otherwise, please, point me to the number between 0.999…. and 1.

The neocortex works sort of like an autoencoder, that takes a million if pixel, and sums it up in a thousand pieces of meaningfulm information.
When your neocortex works, you primary deal with those more abstract meaningful units, everything looks simple, and you are low iq. When the neocortex fails, you are overwhelmed by the raw complexity, deal with much less abstract terms, everything seems insanely complicated, and you are high IQ. You make crazy deductions, as instead of working with a label that means let's say "married couple" you work in much less abstract concepts. What does it mean that they are a married couple? Is it in their hair, eyes, what they're wearing? Explain it to me! What does it mean that she is a women, why can't you explain to me are you stupid? Do you think that I will believe such made up bullshit? Why can't you rationally explain it to me if it's real. I need a 1456 pages treatise to understand all nuances of this.

When and why did we tie "being alive" to "being human" in the discussion surrounding AI?
If a hypothetical AI has no empathy, no ability of original thought by which to create art it is deemed "lesser", not human, not alive and in essence a failure.

When, or maybe a better question is how, will we remove the constraints of humanness from AI development?.

We assume the natural numbers are infinite. If we introduce a greater infinity, to count the natural numbers, we can assume in the same way that they are counted. However, to recite all the natural numbers in 'finite time' is impossible.

It literally does. When you have one proton that exists it is assigned a singular existence by the fact that it can't just fucking duplicate itself. Reality is inherently quantitative and no amount of self delusion on your part about the proper meaning of the semantics will change that. That's why math describes reality, because reality is quantitative. I would have loved to argue about this with you when I was dumb fucking teenager with something to prove, but you are so singularly quantitatively stupid I will concede that you are right anon, reality is qualitative and that is why when we want to understand how to get to the moon we talk amongst ourselves and apply the socratic method to open dialogue debates in the control room

You’ve confused a sexual urge some women might occasionally have with actual affection and romantic interest. Women don’t care about the age of a man conditioned on this: the man is healthy and vigorous for his age. This is a similar issue to observing men like porn starts and therefore must want to start families with porn stars.

You seem to be under the impression that my flat earth hypothesis is "serious". It's not. I don't think the earth is flat. Did you even read my posts? I know how gravity works, at least Newtonian gravity. As for GR, well I did a course but I only know the basics. Back to the hypothesis, obviously it would entail an assumption that gravitational acceleration is also uniform. How would that work? I don't know. As your mom.

the real philosophical problem with artemis was the conceit that you could control costs by lowering the launch cadence. that was the thinking from the start - that we'll keep using expensive shuttle hardware, but we'll launch it so rarely that we can start cutting jobs. and since we're going to the moon instead of LEO, nobody will complain if we only launch once a year. but it's turning out that there isn't some sustainable low-cadence equilibrium. instead nasa's manned spaceflight operations are in a death spiral, with costs per mission rising faster than they can save money by delaying and cancelling missions. and the only thing that might shake nasa out of this 20-year delusion is chinese moonboots.

The problem with old and current science is that you're not asking “why” enough and reflecting on it. You're accepting and assuming. Current science is doomed because it's wrong. It has no future. The only future is new science. Science is understanding, not acceptance. If you actually scrutinize yourself and see everything you've just accepted and assumed, it may be quite shocking.

Honestly my best moments were when I just talked to peers and professors about what we were doing and interested in at the time. They would share some wisdom and points of interest suggesting some books and sections and papers.
I know it all sounds silly coming from an undergrad, but I'm considered among the exceptional students. However, over time I feel totally hollowed out. I always ended up so busy worrying feeling stressed and it all just seems so artificial and pointless, like I was killing myself.

You don't have to go to graduate school to publish papers, it's just harder because you need to learn how to identify tractable open problems in a specific sub niche as well as being extremely motivated. If you think you can do that without graduate school then nothing is holding you back really. You probably also want to attend conferences and network with professors in your specific area of research.

Otherwise just go to graduate school, the academic hazing phase is only a few years then you can focus on learning to conduct research and publish.

Yeah well, I can't tell if they're retarded or I am, so I'm going to choose them by default. It would be fucking stupid for the geometry of spacetime to be malleable and shapeable if it wasn't an actual thing that can interact with matter and energy. The cosmological constant also clearly lays out a mathematical relationship between the shape and expansion of the universe and the rest of the equation, which wouldn't make sense if it didn't exist. Gotta remember that even when Einstein was wrong about whatever the fuck he believed, his math turned out to be totally infallible. That's not about to stop being the case just because some dumbies on 4chan don't understand relativity, but think they do. Also remember not even Einstein understood relativity totally, and he didn't want to work out his own equations because it was too hard. Someone else came up with the swarzchild radius.

oh I'm retarded I thought you replied to my other post. Anyway, I think the other anon was being facetious, and from what I've gathered from the series I've watched on relativity, c is in fact the unifying element from which other relative aspects are understood. But there's a lot of things that go into understanding how things are relative to each other. The speed of light is one of the only rock solid constants that everything can be compared to, but even then they are in some respect relative to the speed of light.
